expand 1/(s^2(s+1)^2)

Solution

expand

\frac{1}{s ^{2} ( s + 1 ) ^{2}}

Solution

\frac{1}{s ^{4} + 2 s ^{3} + s ^{2}}

Solution steps

\frac{1}{s ^{2} ( s + 1 ) ^{2}}

(s + 1)^{2} = s^{2} + 2 s + 1

= \frac{1}{s ^{2} ( s ^{2} + 2 s + 1 )}

Expand

s^{2} (s^{2} + 2 s + 1) : s^{4} + 2 s^{3} + s^{2}

= \frac{1}{s ^{4} + 2 s ^{3} + s ^{2}}
